SPECIFICATION forming part of Letters Patent No. 311,172, dated January 27, 1885.

v Application filed September 17, 1883. (No model.)

To L7/Z whom, t 11i/(Ly concern:

Be it known that I, JOHN BYFIELD, of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Knitting-Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to that class of knitting-machines in which a series of barbed or spring needles are arranged and adapted to be revolved in a circle, and in which mechanism for intermittently throwing into and out ot' ac` tion yarns of different colors is employed, and is an improvement upon the inventions described in my pending applications, filed January 31, 1882, and May 2, 1883, in the United States Patent Oiiice; andit consists in a novel construction and arrangement of the pattern mechanism; Yin certain combinations and arrangements of devices by which the pattern mechanism controls the throwing into or out of action the yarns of different colors, as desired; in a novel arrangement of devices for transferring the joining or splicing of the yarns in the knitted fabric from one side to its opposite, and in a novel construction and arrangement of brushes adapted to lightly rest upon the fabric, for the purpose of brushing the ends ofthe severed yarns attached to the fabric to prevent them from being caught by the needles and knit into the fabric, all of which features will be readily understood by reference to the description of the drawings, and to the claims to be hereinafter given.-

In the drawings, Figure 1 represents a plan of my improved knitting-machine. Fig. 2 represents a rear elevation of same, the head, star-boxes, and severing devices being omitted. Fig. 8 represents a partial leftside elevation of the same. Fig. 4: represents a partial cross-sectional elevation of same, the cutting plane being on line x x in Fig. 2, showingv mounted the landing-wheel7 F and chain-pulleys, its supporting-stand, and a portion of the main table or bed of the machine. Figs. 7 and 8 represent, respectively, a plan and an end view of one of the pattern-links and its connecting-links, one end of the pattern-link being representedin section to show the pivotal connection of the two links. Fig. 9 represents a rear sectional elevation of the mechanism for operating the pattern-chain. Fig. 10 represents a front elevation of the mechanism for operating the cam-bars. Figs. 11land 12 represent rear sectional elevations of the cam-bar, operating-pawls, and the mechanism for acting upon the same. Fig. 13 represents a central vertical section of the friction-wheel and bracket. Fig. 14 represents a front elevation of the brush for operating on the ends of the yarns, showing its relative position as regards the needle-head. Fig. 15 is a partial side elevation of the bar for operating the yarn severing and holding devices, and showing in elevation the devices for disengaging the supporting-latch from the guidelifting rods; and Fig. 16 is a transverse sectional elevation of the same parts, the cuttingplane being on line .00.10 on Fig. 15. Figs. 5,. 7, 8, 11, 12, 18, and 1/1 are drawn to an enlarged scale.

A is the table or bed of the machine, supported u pon the legs A A2, and having mounted in suitable bearings therein the needle-heads B B', which are provided with commonly-constructed bevel gear-wheels at their lower ends, which engage with and are operated by corresponding bevel gear-wheels secured upon the driving-shaft C, mounted in bearings beneath the table A, and adapted to be driven by a suitable belt upon the driving-pulley D. The needle-heads B B have each secured thereon a series of barbed or spring needles arranged in a circle about said head in a wellknown manner. The needle-heads B B are arranged to be revolved about vertical shafts or studs E E, set in a fixed position in any suitable stands or brackets secured to the Aunder side of the frame or bed A, and having secured to their upper ends the stands a and a', which carry the journals, upon which are the knocking-over wheel7 G, in a well-known manner.

H is the stitch-wheel, I the dividingwheel, J the presser-wheel,77 and K the clearing-wheel, all arranged around the outside of each of the circular series of needles and adapted to cooperate therewith in a wellknown manner.

L is the push-back,77 of ordinary construction,adjustably mounted upon the post L in a well-known manner.

l Two, three, four, or more bars, b b b2 Zf, according to the number of colors of yarn to be used,are arranged in suitable bearings, b bib, at the rear of the bed or frame A, each of said bars having secured thereto or formed therelon as many cams or wedges, c c, as there may be needle-heads on the machine, which cams, when said bar is moved toward the right-hand end of the machine, or toward the drivingpulley, act upon and raise one set of the vertical rods d d cl2 dimounted in bearings formed in the shelves dL and d5 on the stands M M. Another bar, e, is mounted in the same manner by the side of the bars b b b2 t, and has secured to its righthand end, or that end nearest the driving -pulley D, the arm or plate e, which projects transversely therefrom and over the ends of the bars b b Zi b3,in such a position as to be acted upon by either of the pins if, set in the upper sides of the bars Z) b b2 b3, in such a manner that the bar @shall be moved toward the right-hand end of t-he machine whenever either of the bars b b b2 if Vshall be moved in that direction, and that either of thetbars b b b2 b3 which has been moved to the right shall be moved to the left again by the movement of the bar e in that direction.

To the stands M M are pivoted the yarnguides ffj"2 f3, operated by the rods d d d2 d, respectively, and provided at their i11- ner ends with suitable eyes, through which the yarns are passed on their way from the bobbins (which are not shown in the drawings) to the needles. Each of the rods d d d2 d3 is surrounded by a spiral spring, so arranged as to tend to force said rod downward when released by the latch di, pivoted to the shelf d5, and held firmly against the rods d d dl di by the spring d, (shown only in Fig. 3,) and adapted to engage with suitable shoulders upon the rods d d d2 di and hold said rods in a raised position, after being lifted, until they are again released therefrom. Vhen one of the rods d d cl2 d is raised by the cam c, which moves beneath it, the inner end of the one of the yarn-guides ff f2 f3 to which it is connected is depressed, so as to throw the yarn across and between the needles in such a manner that the stitch-wheel H will take the yarn and form the stitch in a well-known manner.

The latch d7 is disengaged from the shoulders or notches on the rods d d d2 d3 by means of a pressure being brought to bear upon the inner side of its free end by a suitable lever, d, pivoted to the shelf d5, and havinga downwardly-projccting arm which lies in the path ofthe toe e and in the forward movement of the bar c t. e., the movement toward the ri ght-hand end ofthe machine, said toe engages with said downwardly-projecting arm, and thus moves the lever so as to disengage the latch dT from the rods d d d2 di and allow the spring upon the raised rod to move said rod downward and raise the inner end ofits yarnguide in precisely the same manner as described in my previous application, led May 2, 1883, No. 93,6%, said devices, as applied to my present improvements, bein gillustrated in Figs. 15 and 16.

It is obvious that it is necessary to have one 0f the rods d d dZ di up, and some one of the inner ends of the yarirgnides ff f2 f3 depressed constantly, to knit a contin nous fabric.

N is astand, securely` fastened to the bed A,

and provided with suitable mechanism for cutting the yarns that are thrown out of action with the needles and holding the ends of the saine until again required, said mechanism heilig operated by the cam e3, forming part of and reciprocaing with the bar c.

lt will be seen that the number of bars I) b b2 b3 represent the number of colors of yarns used in knitti ng the fabric, and that ifmore colors are desired more bars must be provided that is, there must be a bar, b, for every color used.

All features thus far described are either old and well-known devices, or have already been described in my former applications, and will therefore need no further mention here, as they form no part of my present invention.

The object of my p resentinvention is to provide a mechanism for operating the cam-bars b b b2 b, which will be cheaper, more durable, casier of adjustment, and less liable to need repair than the mechanism shown in my former pending application, which object is fully accomplished by the mechanism which will now be described.

On the left-hand end of the driving-shaft C is mounted thc bevel gear-wheel O, which revolves therewith, and is adapted to engage with and revolve the bevel gear-wheel P, mounted upon a shaft, P', at right angles to the driving-shaft C, said shaft P being adapted to revolve in suitable bearings, P2 P3, on the under side of the bracket P, which is firmly secured to the frame A. These bevel gear-wheels O P must bear the same relation to each other that the bevel gear-wheels do that revolve the needle-heads B B, so that the shaft P may revolve in unison with the needle-heads B B-that is, the shaft P rotates about its axis once to every revolution of the necdleheads B B about their axes.

Immediately below the bars b b b2 b3 is mounted, in suitable bearings, gg', the iat bar Q, which is provided at its right-hand end with the head or crosspiece g2, which is IOO IIO

IOl

provided with as many dogs g3 gt g5 ya as there arebars b b b2 b3, immediately beneath which they are placed, as shown in Fig. 4L.l

To each of the dogs g3 g* g5 g is pivotcd at its front end (or that end nearest the righthand end of the machine) the pawl gl, the front end of which is held in a raised position by the spring g8.

Above each of the dogs g3 g4 g5 g is placed a spring, g, which depresses said dog and pre- 'Y vents the engagement of the pawl connected thereto with the notch bB of the one of the bars I b b2 b3 situated above said pawl and dog when the bar Q is making a forward movement. This reciprocating movement of the t bar Q is imparted by the action ofthe eccentric cam-wheel Q' upon the forked bracket Q2, adj ustably secured to the bottom side of the said bar Q, said eccentric canrwheel Q being firmly secured to and revolving with the shalt P', so that the bar Q, with its pawls gl, moves forward and then backward with every revolution of the needle-heads B l.

The dog gt and pawl g7 are shown in their normal position in Fig. ll, being held thus by the springs gS g, and in this position may reciprocate beneath the bar b for an indefinite length of time without being liable to engage with the notch b8 thereof; but when it is nec essary for the color of yarn to be knit into the fabric, which color of yarn is represented by the bar b', a pin, 71, mounted in a suitable bracket, R, secured to the frame A, is raised so as to lie in the path of the lug or projeo tion glo of the dog g4, and be struck thereby in the backward movement of the bar Q, thus raising the dog gt against the force of the spring g", and allowing the pawl gl, by means of the pressure brought to bear thereon by the spring g8, to engage with the notch bs, all as shown in Fig. 12. It is obvious that with the next movement of the bar Q and pawl gl the bar b will also be moved forward, operating the yarn-guide f' in a manner already de scribed.

As heretofore described the bar b in its forward movement carries with it the bar e, the object ofwhich has also heretofore been described. Vhen the bar e is at its extreme forward position, the projection e, secured thereto, is in contact with the adjustable shoulder e5 of the cross-piece g2 of the bar Q, and when said bar Q returns to the left-hand end of the machine it carries therewith the bar e by means of the action of the shoulder e3 upon the projection or bracket et, and the bar e, by the action of the plate e upon the pin b6 of the bar b', returns said bar to its normal position.

It is necessary that ,when the lug or projection gw of any one ofthe dogs ggtgg6 is raised by its (2o-operating pin h, the detent-notch b8 should be immediately above the co-operating pawl, so as to readily be engaged thereby, and in order to accomplish this the forked bracket Q2 is made adjustable upon the bar Q,

so that the relation of the pawls gigT to the detent-notches 218 bs may be nicely adj usted,as follows: The bracket Q`l is attached to the bar Q by means of two screws,,(one only of which is shown, and that in Fig. 1,) which pass through suitable slots, i', in said bar into the forked bracket Q2, holding the same securely to said bar Q when said screws are tightened, clamping the bar Q between their heads and the bracket Q2. By loosening the screws i they may be adj usted endwise in the slots Qthereby adjusting the bracket Q2 in its relation to the bar Q.

While the operation of only one pin, dog, pawl, and bar is mentioned, it is obvious that any of the co-operating sets are operated in the same manner.

The pin-bracket Ris madein skeleton form, having an upper shelf, j, and a lower shelf,j, in which the pins h h are adapted to slide in suitable bearings. A little below its center of length the pin h is provided with a transverse pin, j, which rests upon the lower shelf, j', thus regulating the distance that the pin 7L may extend below the under surface of the bracket R. Between this pinj2 and the under surface ofthe upper shelf, j, is placed a spring, js, coiled about the pin 7L. and adapted to hold it in position-i. e., with the pin f2 resting upon the upper surface of the lower shelf, j. The bracket R is provided with as many of these pins h as there are cam-bars, under which they may be placed.

The construction and arrangement of the stand or bracket R and its attendant parts will readly be seen by reference to Figs. 4, 11, and 12. Beneath the bracket R is placed t-he patternchain, hung upon the loose pulleys S S', mounted upon suitable journals attached to the frame A, said chain being additionally supported by the bracket S2 and the sliding guidecarriage S3 as it passes beneath the bracket R. This patternchain is made up of a number of pattern-links S* and small connectinglinks S5,

ICO

constructed and arranged in such a manner that when the chain is passing over the bracket S2 and the sliding guidefcarriage S3 the pattern-links form a continuous and uniform surface, as will be readily seen by reference to Figs. 1, 2, 7, and 8. The intermediate or connecting links, S5 S5, are hinged to the pattern-links Sl S, as shown in section in Fig. 7, by a long pin, S, passing from one side of the pattern-link through the connecting-link S5, and lapped into the opposite side of the pattern-link S4, said piu being provided with a suitable slot, by which it may be readily removed to allow eXtra links to be inserted into the pattern-chain when a longer pattern is desired. The upper side of the outer edge of pattern-links are provided with a series of ratchet-teeth, 7c It, of an equal distance apart, which are adapted to be engaged by the pawl k', actuated by the leaf-spring Ict, and pivoted in a suitable slot to the rod k3, adapted to reciprocate in the bearings kt if, as shown in Figs. 2 and 9. To the left-hand end, or that end nearest the shaft P, is secured the fork la, which is provided with a bearing, k7, in the bracket P1. This fork is secured to the rod k3, so that, by means of the reduced threaded end ks and nuts k cJ, the pawl k may be slightly adj usted so as to bring each transverse row of pattern-holes k10 to its proper position relative to the pins h 7L of the bracket It. Each pattern-link has provided therein as many transverse rows oi" holes kw as there are ratchet-teeth upon said link, the centers of said rows of holes 7cm 7cm being directly opposite the center of said teeth kk. These holes k1" k1 are provided with female threads, into which are adapted to be screwed the pattern-pins Z Z, which are adapted to raise thc pins h It of the bracket R in the passage ol" the pattern-chain beneath the same, the object ot' which has been fully explained. The two arms ot the fork It pass downwardly on either side ot' the eccentric cam-wheel ku, securely attached to the shaft P, with which it revolves, acting alternately on either arm of the fork k, thus giving a forward and backward movement to the rod 7c3 with every revolution of the needleheads B B. The amount of movement ofthe rod k3 is such that with every reciprocation of said rod the pawl k moves the pattern-chain toward the lett-hand end ofthe machine a distance equal to the length of one ofthe teeth liv. thus allowing each transverse row of holes k1" kw to take a position successively beneath the pins 7L 7L of the bracket It.

As itwould take an extremely long` chain to take in a pattern that would make a pair ot' long stockings made of iine yarn if only asingle series ot' holes are used-. c., a row of holes lengthwise ofthe pattern-chain for every pin h in the bracket R-l provide mechanism by which any reasonable number of series may be used, which in the machine shown in the drawings is three. To accomplish this object the pattern chain, in passing beneath the bracket R and pawl k, passes over the sliding carriage Sis and between the vertical sides thereof, thus preventing any lateral movement of the chain without the aid of the carriage S3, as shown in Fig. et. rests upon and is adapted to move transversely of the broader bracket S7, which is firmly secured to the frame A, so that the upper surface of the carriage Sii is even or on a level with the bracket S2.

To the under side of the carriage S3 is secured the toe m, adapted to move toward and from the machine in the slot m ofthe bracket S7. The toe m, and with it the carriage S, is pressed firmly toward the machine by the spring m2, acting upon said toe.

Between the carriage S3 and-the frame ot' the machine is placed the tootaed cam-wheel T, loosely mounted upon a suitable journal in a bracket, T, secured to the under side ofthe bed of the machine, said cam-wheel extending upwardly through a slot in the bracket The carriage S S7, so that the teeth of said wheel lie in the path of the pin T2, secured to one of the-pattern-links S. On the outerside of saidwheel T project the cam-throws a a a2, or as many throws as there are series of holes 7c10,or a multiple of that number, which in the machine shown in the drawings is six, there being threev series of holes in the pattern-chain. There must be a tooth on the circumference of the wheel to correspond to each throw on the face.

The operation of this mechanism is asfollows: At the commencement of a pattern the toe in should rest against the face of the wheel T, and the pin T2 should be immediately to the left of the said wheel T, and in this position the pins h h hh of bracket R would be immediately above the iirst series of holesnamely, l, 4, 7, and 10, as shown in Fig. 7d and they all remain in this position until in the rotation ot' the pattern-chain the pin T2 reaches the toothed cam-wheel and in its passage comes in contact with one of the teeth thereof, moving the same about its axis, so that the toe m is made to rest upon the second elevation, n, moving the carriage S3, and-with it the chain, thus causing the pins h 7L h h to be above the second series of holes 2 5 8 1l, in which position they remain until the pin TZ in its rotation moves the next tooth, so as to move the toe m to the third elevation, a2, by a similar operation, thus causing the carriage to move again, so that the pins h h h h are overthe third series ot' holes,3 6 9 l2, in which position they are shown in the drawings. The next time the pin T2 moves the wheel T it causes the elevation a2 to be moved from the path ofthe toe m,which is immediately forced by the spring m2 against the lowest elevation, ot, thus bringing the carriage S3 to its starting-point, when the operation commences again with a new pattern and anew pair of stockings.

It is obvious that the pin T2 should move each tooth ofthe wheel T with which it comes in contact a distance equal to its length-z'. c., one-sixth of the distance about its axis where there are teeth, and one third where there are only three, 82e. To allow of this lateral movement of the pattern-chain` the pulleys S S, upon which it is supported, areeach loosely mounted upon a journal somewhat longer than the hub of said pulley, so that each of said pulleys is easily moved with the pattern-chain as that is moved by the carriage S, the object of which is obvious, Fig. 6. The pulley S, at the lett-hand end of the machine, is made square, as shown in Fig. 2, so that the pattern-chain will fit about said pulley on its passage from the carriage Sis without any binding thereon. The pulley S is made round, as any unevenness of the patternchain has time to become rectified before reaching the carriage S3. Thejournal U, upon which the pulley S is mounted to accommodate the varying length of the patternchain, is made adjustable upon the slotted 'soY IOO

IIO

bracket U, which is firmly secured to the unl der side of the bed A, and which is shown in the drawings in Figs. 2 and 6.. The journal U is provided with the enlarged end U2, which is flattened on opposite sides of its inner end, as at o, so as to iit the slot 4o of the bracket U', in which it is adjusted lengthwise of the machine. The said end U2 is also provided with a reduced threaded portion, o, upon which operates the nut o3, to firmly clamp the bracket U between said nut and the shoulders o? ol of the enlarged end U2, all in au obvious manner, Fig. 6.

To the standard V, secured to and moving with the carriage S, is adjustably secured the stud V', upon which revolves the frictionwheel V2, constructed of several disks 0fleather, p p, riveted together between two disks of metahp'p'. By loosening the nut p2 and turning the screw p3 the disks of leather p p may be adjusted to or from the ratchet-teeth 7c k of the links S, upon which they press. The object of this is to regulate the friction upon the pattern-chain so as not to allow its own weight to carry it a number of teeth when once started by the pawl k', as was found to be the case when this was not in use. By its proper use the desired tooth-by-tooth movement of the pattern-chain is easily obtained.

The joinings of two different colors are made in a straight line the whole length of the fabric, as the machine has been described 5 but this is very objectionable, as it causes the joinings to come on the front of every alternate stocking. Y To overcome this objection it is necessary to change thejoinings to the opposite side ofV the fabric while knitting the feet of the stocking. which causes the joinings to be formed in a straight line at the back ofthe leg of each stocking. To accomplish this the bevel gear-wheel P is loosely mounted upon the shaft P', upon which is securely fastened the collar P5., having provided upon its front face the two pins q q, which engage with corresponding pins, g q', upon the rear face of the hub of the bevel gear-wheel P, and from which power is transmitted from said gear to said shaft P. bearings P`Z P3 of the bracket Pt, so as to allow a lengthwisemovement therein.

Between the bearing P3 and the eccentric cam-wheel 7c,and around the shaft P,is coiled a powerful spring, P, which tends to keep the pins q g g q engaged so that a continuous ro` tary motion is given to the shaft P by the bevel gear-wheel P unless otherwise acted upon.

To the leg A', at the left-hand end of the machine, is rm] y secured the bracket WV, provided at its outer end with a suitable bearing, W', in which the rod W2 is mounted, the axis of which lies in a line with that of the shaft P. The front end of the rod W2 is pivoted to the lever W3, provided with the handle WV, and having its fulcrum in the ear or projection W5 of the bracket W,all as shown in Figs. l and 3.

The shaft P is mounted in thel While the legs of the stocking are being knit a continuous rotary movement is given to the shaft P', as has already been described; but `as soon as it becomes necessary to change thejoiuings to the opposite side of the fabric while the feet are being knit, the handle NVt, and therefore the lever Vi, is quickly pressed to the rear of the machine, and all pressure immediately removed therefrom. This movement of the lever W3 presses the rear end of therod W2 against the front end of the shaft P, moving it backwardly in its bearings l?2 P3, thereby disengaging the pins g q from the pins q q of the bevel gear-wheel P, which is kept from moving endwise with the shaft P by the bracket P7, secured to the bracket Pt, and having formed on its outer enda suitable fork tted to the groove PS, formed inthe hub of said bevel gear-wheel P. The bevel gear-wheel P, being continually in motion, moves the pins q q thereon by the pins q q of the collar P5, and makes a half-revolution, when the pins q q once again engage with the pins q q, which have been moved forward by the force of the spring P upon the cam-wheel k, as soon as the pressure has been removed from the lever W3. It is obvious that this movement of the lever W3 will cause the shaft P and all parts connected thereto to remain stationary while the heads B B are making onelhalf a revolution, thus causing the j oinings to be made after the said movement to be made on the opposite side of the fabric from those already made. After one color of yarn has been knit into the fabric and another cut off, the ends of these yarns are apt to get caught by the nee` dles and knit into the fabric,which is very objectionable. To prevent this, I provide the brush Y, (shown in Figs. l and 14,) which is placed so as to rest upon the fabric immediately over the knocking-over wheel G, being rmly pressed thereon by the spring Y', to wliich it is attached, said spring` being se cured to the bed A by the screw Y. In this position the brush causes the ends of the yarns to be carried up ward and clear of the needles,

preventing any engagement therewith. By

loosening the screw Y2 the brush may be swung about its pivot out of the way of the operator when adjusting the parts of the needie-heads B B', or when commencing a' new tube of knitting.

In another application of mine, iiled in the United States Patent Office January 3l, 1882, is shown and described a revolving brush for the same purpose as my present stationary brush, which latter is a great improvement upon my former invention, for the reason that itis much cheaper, more readily removed or adjusted, and, iu fact, works better.
